Evaluating Your Hearts’ Blood Supply and Function Through:
Nuclear Imaging
Helping your physician evaluate your heart’s function and locate exactly where the heart muscle may not be receiving enough blood.

What to Expect
Nuclear imaging can n=be done in a hospital or in an outpatient healthcare facility. An electrocardiogram is usually taken before nuclear imaging begins. An IV, or intravenous catheter, is placed in the arm to administer the tracer. The patient lies on his or her back on a padded table under a camera. A small amount of tracer is injected into the catheter, and then the camera moves, capturing images at different angles or rotating slowly around the patient.

Pre Test Guidelines
Patients are advised to avoid the following prior to nuclear imaging:
· Smoking
· Drinking alcohol
· Drinking caffeinated beverages
· Taking nonprescription medications
In some instances, patients may be asked to discontinue a prescription medication.

Risk Factors for Possible Complications
Nuclear imaging is not advisable for pregnant or nursing women.
Nuclear imaging scans are usually completed in 4 to 6 hours.

Possible Complications
Complications associated with nuclear imaging include a slight risk of developing angina or arrhythmias.

Post Test Guidelines
Patients are instructed to drink fluids to help flush the radioactive tracer.

About Nuclear Imaging
During nuclear imaging, a small dose of a radioactive isotope is injected into the bloodstream. The radioisotope, or tracer, is carried through the bloodstream and into the myocardium, of heart muscle. Special cameras detect the radiation released from the tracers and record information about the heart muscle and blood flow. This information is then used to produce images of the heart on a computer screen or film. The radioactive isotopes used in nuclear imaging lose their radioactivity quickly and typically pass from the body within 24 hours.

Among the types of nuclear imaging are:
· Myocardial perfusion scan which is used to evaluate blood flow
· Radionuclide ventriculography which measures ejection fraction, stroke volume, and cardiac output
